The layout is very important. It should be uncluttered, with lots of white space.
There should be large gaps between paragraphs.
Pictures should be placed next to the paragraph they refer to.
Documents should normally be no longer than 20 pages. But we would be happy to make a longer documents if:
- It is a questionnaire - because people do not linger on each page
- Or a reference document - because people don't read the whole document at one time.
We like contents pages because they help people to see the structure of the document and find things quickly.
